2 results about "Engine displacement" patented technology

The invention discloses a hybrid power parameter determination method and device and electronic equipment, and relates to the field of vehicle design, and the method comprises the steps: determining the engine displacement of which the average operation power of an engine is consistent with a target fuel consumption area according to the average operation power, the torque standard deviation, the maximum torque fluctuation value and the fuel type in a vehicle road spectrum; according to the method, the determined engine can work in the interval with higher efficiency, the fuel economy is improved while the conventional power requirement is met, and the engine cost is reduced. The rated power of the motor is further determined according to the maximum operation power in the vehicle road spectrum and the target engine external power, and the target engine external power is the external power corresponding to the target vehicle speed or the target rotating speed under the maximum operation power. And determining the battery capacity according to the rated power of the motor, the climbing duration in the vehicle road spectrum and the battery adjustment coefficient. And on the basis of the engine, motor driving is matched to increase the endurance mileage, and the economy of the whole vehicle is improved.

The utility model relates to turbocharger field, and disclose a kind of anti-leakage turbocharger, including supercharger shell, the one end of supercharger shell is provided with air inlet pipe and air outlet pipe, the other side of supercharger shell is provided with turbine cavity, the inner chamber of turbine cavity is provided with turbine main body, this anti-leakage turbocharger, by the bolt two in recess, in turn under the action of limiting block in limiting groove, drive circular table to move to left side, in turn under the action of moving block and limiting rod in moving groove, drive turbine blade to move to the outside of turbine main body, to increase turbine overall diameter, provide higher supercharging pressure, to increase the power and torque of engine, so that its air intake meets engine power demand, solve the problem that current turbocharger is difficult to adjust turbine size according to engine displacement.
